General Instructions This essay should be 400-500 words in length. You must use correct spelling and proper mechanics. You must include citations and a reference list for any resources used at the end of this essay. It is expected that you will use one to two references for this essay topic. Essay #2 Studies of identical and fraternal twins have yielded some very interesting information on the genetic basis of behavioral traits. Read both of the following articles from the web, and then complete the assignment below. · Do our genes make us popular? From Scientific American http://www.scientificamerican.com/article/popularity-genes/ · Minnesota Study of Twins Reared Apart, from the Minnesota Center for Twin and Family Research http://mctfr.psych.umn.edu/research/UM%20research.html Address the following questions in your essay: · What is most striking to you in the results presented in the two articles? · In the article on popularity, do you agree with the conclusion that there is a genetic basis to how popular people are? Explain why or why not. · In the twin studies, do you think that the behavioral similarities in identical twins raised apart from birth (like “the Jim Twins”) are due to inheritance? Explain why or why not. · Conclude by stating whether or not these two articles have changed the way that you think about genetics, and explain your answer.

Read “Point of No Return” and “A GlobalOverview on Consanguinity”.

Based upon what you have learned and your reading of “Point ofNo Return,” do you think it is possible that inbreeding couldactually result in optimal homozygous conditions that create a“fitter” population than that possible with heterozygouspopulations? Can inbreeding be good for a population? In a coupleof paragraphs, justify your answers to these questions.

In one paragraph, discuss these questions. Is consanguinity anissue in the United States? What about in other parts of the world?Answer in 500 words or less.

Article : “The ‘Domestication Syndrome’ in Mammals: A Unified Explanation Based on Neural Crest Cell Behavior and Genetics” by Wilkins, Wrangham and Fitch, Genetics, Vol 197, pp. 795-808, 2014.

Questions

a) What is the ‘Domestication Syndrome’? What traits that are part of the syndrome are intentional targets of the domestication process? What traits are not? Why might animal breeders target the traits that they do?

b) The paper focuses on neural crest cells and tissues derived from them. What is the neural crest? How are so many tissues and organs affected by neural crest cells?

c) The paper presents an explanation for the Domestication Syndrome. Summarize it and give specific details about how neural crest cell proliferation affects each trait.

d)What types of evidence is used to support neural crest cell effects on each of the traits discussed? Why do you think evidence of that type exists (be specific for each trait)?

e)What are the alternative explanations for domestication syndrome (compared to what the paper suggests)? Can it be explained by “relaxed natural selection,” “phenotypic plasticity,” or “gentler living conditions”? How and Why? Come up with some of your own alternative explanations for the syndrome.

f)Suggest ways to test the Neural Crest cell explanation of Domestication Syndrome, and any alternatives you can think of.
